Midterm Flashcards
Monomers
individual molecules
Polymers
multiple molecules
Organic Compounds
carbon based
Inorganic Compounds
do not contain carbon, water!
Cohesion
water sticks to itself
Adhesion
water sticks to others
Capillary Action
adhesion and cohesion working together
EX. In the straw
High Specific Heat
water holds on to the hot and cold temperatures
Surface Tension
light layer on top of water because of cohesion
Universal Solvent
… because water is polar
Deydration Synthesis
the process of joining two molecules (or compounds) together following the removal of water.
Hydrolysis
two molecules separating and using water to do so.
Covalent Bonds
two atoms share one or more pairs of outter shell electrons.
Ionic Bonds
attractions between ions of opposite charge.
Hydrogen Bonds
A type of weak chemical bond formed when the slightly positive hydrogen atom of a polar covalent bond in one molecule is attracted to the slightly negative atom of a polar covalent bond in another molecule.
Disaccharides
formed by dehydration synthesis and two monosaccharides.
EX. maltose, lactose, sucrose (C12H22O11)
Monosaccharides
individual carbohydrate molecule.
EX. glucose, frucose, galacose (C6H12O6)
Polysaccharides
thousands of monosaccharides linked together (carb.)
EX. Cellulose- enclose plant cells, Glycogen- store carbs short term, Chitin, Starch- plants store glucose for long term
Carbohydrate Purpose
supply energy and dietary fiber
** structural componet of cells: cell wall (cellulose- chains of glucose in cell wall)
Lipid Purpose
store energy, protection of organs, insulation for neurons
** Componet of cellular membranes
Catagories of Lipids
Fats, Oils, Waxes, Steroids
Saturated Fats
no double bonds so solid
Unsaturated Fats
double bonds so liquid
Triglicerides
lipid monomer, 1 glycerol and 3 fatty acids
Phospholipid
1 glyerol, 2 fatty acids, 1 phosphate group
** hydrophilic and hydrophobic ends**
Amino Acids
building blocks of proteins
Polypeptides
joined amino acids (proteins)
Protein Purpose
MANY: structure, transport, antibodies, enzymes, storage
Nucleic Acid Monomers
Nucleotides
Nucleic Acid examples
DNA, RNA, ATP
Nucleic Acid Roles
- contain genetic information passed on to new cells or during reproduction
- instructions to make proteins
- ATP
ATP
Adenosine + Ribose + 3 Phosphates = Adenosine Triphosphate.
DNA Nitrogen Bases
- Adenine
- Thymine
- Guanine
- Cytosine
RNA Nitrogen Bases
- Adenine
- Uracil
- Guanine
- Cytosine
